Description
Overview
The HOBO by Onset U24-002-C is a cost-effective data logger designed for measuring salinity, conductivity, and temperature in saltwater environments. It uses a non-contact sensor that provides long operational life and easy access for cleaning and maintenance. The device is ideal for aquatic biology and hydrology research projects, monitoring saltwater bays, upwelling events, rainstorms, and discharge events. It can also gather salinity data for compensation of HOBO U26 Dissolved Oxygen logger readings.
Note: When monitoring salinity in waters with variations exceeding ±5,000 uS/cm, refer to the product specifications for accuracy verification. Monthly field calibration is typically required for optimal accuracy.
